D-Link DWM-156 is detected but doesn't work

[Aneesh Neelam]

I have a D-Link DWM-156 HSPA Modem, that I bought just a few days ago. The modem has drivers in its internal storage. There are Debian Software Packages for both i386 and amd64, so obviously I installed the amd64.deb using Software Center: 3g_modem_connect_D300_amd64.deb . Then manually, I did: "sudo modprobe usbserial vendor=0x2001 product=0x7d01". I have confirmed that the device switched to usbserial mode from usb-storage mode. As the product ID was a706 before.

But here is the thing, the device is detected and I get the Mobile Broadband options in the Network Menu ONLY when a SIM Card is NOT present in the modem. If a SIM Card is present, the Modem switches to usbserial mode but after that, there is no change in the network menu. I can't use my modem in Ubuntu at all, due to this.

I have uninstalled the package usb-modeswitch, but there is no change in behavior. The modem is detected when there is no SIM Card present and the network menu shows Mobile Broadband options. But with a SIM Card, the network menu does not show Mobile Broadband.

And my laptop is the Dell XPS L502X and is almost 1.5 years old. I always plug my modem into the USB 2.0 port. Everything else works prefectly (Nvidia with Bumblebee of course)

I have installed usb-modeswitch again.
Now the modem is not recognized at all, even with the SIM Card removed.

[Aneesh Neelam (aneesh-neelam)]

$lsusb
"Bus 002 Device 023: ID 2001:7d01 D-Link Corp."

Modem is detected and it is in usbserial mode.
But the network menu doesn't show anything even after "sudo modprobe usbserial vendor=0x2001 product=0x7d01"
